About the formats
bzip2 file
BZ2 (bzip2) compresses a single file more tightly than gzip, using block-sorting compression. Like gzip it handles one file at a time and is paired with TAR to bundle many, as a .tar.bz2.
Strengths
- Better compression than gzip
- Common on Unix-like systems
- Good for single large files
Limitations
- Slower than gzip
- Compresses only one file at a time
- Not native to Windows
Best for: Tightly compressing a single file — repacked into ZIP or a tarball to bundle several.
7z archive
7z is the native format of 7-Zip, using LZMA compression to squeeze files far smaller than ZIP. It supports strong AES-256 encryption and solid archives, at the cost of needing 7-Zip-compatible software.
Strengths
- Excellent compression ratio
- Strong AES-256 encryption
- Handles very large archives
Limitations
- Needs 7-Zip-compatible software to open
- Slower to compress
- Less universal than ZIP
Best for: Packing large collections as tightly as possible when recipients can use 7-Zip.
